About the test
Take control of your health with a Full Blood Count Test (FBC including DIFF) - the first step in identifying potential health issues and monitoring and diagnosing disease. Abnormal FBC results can be indicators of serious conditions such as anaemia, infections or blood disorders. Our CQC-regulated laboratory ensures rapid, accurate results for 15 biomarkers and ratios, including white blood cells, red blood cells, platelets, haemoglobin and more.
You’ll also get free access to our online Health Dashboard, which allows you to track your results over time and provides actionable ways to improve your health.

What is a Full Blood Count Test?
A full blood count test (FBC) is a set of medical laboratory tests that provide information about the cells in your blood. 15 biomarkers and ratios are worked out during the analysis, including:
- White blood cell count
- Red blood cells and platelets
- The concentration of haemoglobin
- The haematocrit (the volume percentage of red blood cells)
- DIFF count
Also included are the red blood cell indices, which indicate the average size and haemoglobin content of red blood cells, as well as the white blood cell differential, which counts the different types of white cells is also included.
Conditions like anaemia and thrombocytopenia are defined by abnormal full blood count test results. The red blood cell indices can provide information about the cause of a person's anaemia such as iron deficiency and vitamin B12 deficiency, and the results of the white blood cell differential can help to diagnose viral, bacterial and parasitic infections and blood disorders like leukaemia.
Before you book
The FBC is often the first step of many medical assessments and can be used to monitor or diagnose disease. As with any test, full blood count test results are compared to reference ranges and interpreted thereafter. The reference ranges generally vary with sex and age, so if you are booking this test, make sure that you provide us with an accurate date of birth and your reference sex.
We offer this test as both capillary and venous sample options. However, this test is extremely time sensitive and the sample deteriorates very quickly, so you must send it to us in-line with exact instructions for posting (Monday to Thursday, before 12:00, taken in the morning before posting, found with your kit). If the sample deteriorates substantially - we will only report the essential parameters and will not offer a retest. If the sample is completely unusable due to delay in the post - we will, of course, offer you a retest. We advise you to have this test as a venous option, at one of our clinics, for a much more predictable experience.
Not all results falling outside of the reference range require medical intervention, please consult your GP.
